Mostly as a consultant, but always as a leader, I have worked
at many blue chip employers and clients over the years in a variety
software related roles. Sometimes direct, and sometimes as a consultant though ThoughtWorks (I was there 12.5 years).
Roles have either been:
Delivery: coding and shipping of solutions (architect, developer, test engineer)
Executive: chief of, head of, some group/division/function
Advisory: permanent or contract lean/agile/devops expert
